Description

  The present invention relates to a hologram makeup method for imparting a rainbow-colored glitter effect by holography to horny skin such as hair, eyelashes, mustaches, nails and skin.

  It has been proposed that a hologram pigment is used in cosmetics such as lipstick, nail polish, and nails to obtain a rainbow-colored glitter effect by makeup (Patent Documents 1 and 2).

  In order to obtain the same cosmetic effect, it has been proposed to apply a nail enamel containing a polyurethane emulsion in advance to the nail and transfer the concavo-convex pattern of the diffraction grating having the concavo-convex structure to the coating film ( Patent Document 3).

  However, with the conventional method using a hologram pigment, only the effect that bright spots are scattered sparsely is obtained for hair such as hair, eyelashes, and mustaches. Cannot be shining.

  Even by the method of transferring the concave / convex pattern of the diffraction grating to the nail enamel coating film containing the polyurethane emulsion, it is difficult to obtain a bright effect that can be sufficiently observed under normal room lighting. In this method, once a nail enamel coating film is formed on the hair, it is not easy to remove it. Therefore, it is difficult to enjoy it easily only when a consumer desires hologram makeup for hair.

  On the other hand, the present invention makes it possible to perform hologram makeup capable of sufficiently observing the glitter effect under normal indoor lighting on hair such as hair, eyelashes, and mustaches, The purpose is to make it possible to easily remove the makeup by a washing action such as face washing.

  The present inventor has found that the above-mentioned object can be achieved by using a diffraction grating having a concavo-convex structure such as a hologram sheet as a template when a film-forming polymer is used and a dry film of the solution is formed. Was completed.

  That is, the present invention provides a polymer solution in which the surface irregularities of the diffraction grating are transferred by interposing a film-forming polymer solution between the stratum corneum and the diffraction grating having an uneven structure, and drying the polymer solution. A hologram makeup method for forming a dry film on the keratin is provided.

  The present invention also provides a hologram cosmetic comprising a hologram sheet and a film-forming polymer solution.

  According to the hologram makeup method of the present invention, the hologram makeup based on the surface irregularities of the diffraction grating can be sufficiently observed even under normal room lighting for the stratum corneum such as hair, eyelashes, mustaches and nails. In addition, the hologram makeup can be easily removed by a cleaning action such as daily shampoo or face washing, if necessary.

  Hereinafter, the present invention will be described in detail with reference to the drawings. In addition, in each figure, the same component represents the same or equivalent component.

  FIG. 1 is a schematic explanatory view of one embodiment when the hologram makeup method of the present invention is applied to hair.

  In this embodiment, generally, first, the polymer solution 2 is applied to the hair bundle 1a of the hair 1 ((a) in the figure), and the hologram sheet 4 is overlaid thereon as a diffraction grating having an uneven structure, A polymer solution 2 is interposed between the hair 1 and the diffraction grating surface of the hologram sheet 4. Then, in this state, the polymer solution 2 is dried ((b) in the figure). Thereby, the surface irregularities of the diffraction grating of the hologram sheet 4 serve as a mold, and a transfer pattern of the surface irregularities of the diffraction grating of the hologram sheet 4 is formed on the dry film 3 of the polymer solution 2. In the present invention, as a method of interposing the polymer solution 2 between the hair 1 and the diffraction grating surface of the polymer sheet 4, the polymer solution 2 is applied to the polymer sheet 4 in advance, and this is applied to the hair 1. You may overlap.

  Thereafter, the hologram sheet 4 is peeled from the hair 1 ((c) in the figure). As a result, the hair 1 is coated with a dry film 3 of the polymer solution 2 having a transfer pattern of the surface irregularities of the diffraction grating of the hologram sheet 4, and is rainbow-colored so that it can be sufficiently observed even under normal room lighting. The brilliant effect is exhibited. In the state in which the hologram sheet 4 is peeled off, the hair bundle 1a is formed by bonding the hairs 1 one by one with the dry film 3 weakly. Therefore, the hair bundle 1a is loosened and each hair 1 is made independent. ((D) in the figure).

  Thus, in the present invention, when the polymer solution 2 forms the dry film 3, the transfer pattern is formed on the dry film 3 of the polymer solution 2 using the surface irregularities of the diffraction grating as a template, so that it is already formed. Compared to applying a diffraction grating to a coating film such as polyurethane emulsion and pressurizing it to form a transfer pattern of the diffraction pattern on the coating film, the surface irregularity of the diffraction grating can be accurately transferred. The rainbow effect can be increased.

  In the present invention, as the polymer solution 2 described above, a polymer solution capable of forming a film, that is, a film containing a film-forming polymer dissolved therein is used. Thereby, the surface irregularities of the diffraction grating can be accurately transferred to the dry film 3 of the polymer solution 2.

  In the present invention, as described later, water, ethanol, or a water / ethanol mixed solvent is used as the solvent, and the polymer solution 2 forms a film by drying, and the formed film is water, ethanol, or water / ethanol. It can be dissolved in a mixed solvent or the like. As a result, the film can be easily washed away by a washing process such as shampoo, so that the hologram makeup can be easily enjoyed in a desired scene.

Such a salt is not particularly limited, and is an alkali metal salt such as sodium or potassium; ammonium salt, ethanolamine, diethanolamine, triethanolamine, 2-amino-2-methylpropanol, 2-amino-2-methyl- Mention may be made of organic base salts such as 1,3-propanediol, aminomercaptopropanediol, triisopropanolamine, glycine, histidine and arginine. Of these, salts of 2-amino-2-methylpropanol and 2-amino-2-methyl-1,3-propanediol can be preferably used.

  Moreover, about what has a basic group, what neutralized a part or all of the basic group and converted into the salt is preferable. Such a salt is not particularly limited, but as an inorganic acid salt, a salt of an inorganic acid such as hydrochloric acid, sulfuric acid or phosphoric acid is preferable, and as an organic acid salt, acetic acid, lactic acid, glycolic acid, dimethylolpropionic acid Salts of organic acids such as tartaric acid, citric acid, maleic acid, malic acid and pyrrolidone carboxylic acid are preferred.

  In the polymer solution 2 used in the present invention, these polymer concentrations are preferably from 0.1 to 20 wt%, particularly from 0.5 to 5 wt%, from the viewpoint of viscosity at the time of coating and transferability of the diffraction grating.

  The polymer solution used in the present invention may contain a thickener in order to prevent dripping of the polymer solution applied to the hair. As the thickener, for example, various water-soluble organic or inorganic polymers can be used. The organic polymer may be any of natural polymer, semi-synthetic polymer, and synthetic polymer. Specific examples of natural polymers include plant polymers such as guar gum, locust bin gum, quince seed, carrageenan, gum arabic, gum tragacanth, pectin, mannan and starch, microorganisms such as xanthan gum, dextran, succinoglucan and hyaluronic acid.

  The blending amount of the thickener in the polymer solution depends on the type of the thickener, the type of the film-forming polymer, and the like, but is preferably 0.01 to 1.0 wt%.

The polymer solution used in the present invention may contain a dark colorant such as black. If the area behind the surface irregularities transferred to the dry film of the polymer solution is brightly colored, it is difficult to distinguish the glitter effect due to the surface irregularities due to the reflected light from there. By making the region darker, the glitter effect due to surface irregularities is more easily observed.
As the colorant, carbon black or iron-based composite pigment is preferable.

  As a solvent for the polymer solution, it is preferable to use water, ethanol or a water / ethanol mixed solvent from the viewpoint of solubility and safety. From the viewpoint of improving the drying property, a 0.1 to 50 wt% aqueous solution of ethanol is preferable. Further, this aqueous solution may be filled in a sealed can together with a propellant to form an aerosol.

  In addition to the polymer solution used in the present invention, various additives usually used in hair cosmetics as necessary, for example, bactericides, as long as the transferability of the surface irregularities of the diffraction grating is not impaired. , Preservatives, antioxidants, ultraviolet absorbers, fragrances, pigments and the like can be appropriately blended.

  Application of the polymer solution 2 to the hair 1 may be performed using a brush, a spatula, a comb, a comb-attached container, or the polymer solution 2 may be sprayed as an aerosol. Spraying the polymer solution 2 as an aerosol is preferable because the drying time can be shortened by the volatilization action of a propellant such as dimethyl ether or LPG contained in the polymer solution 2.

  On the other hand, as the hologram sheet 4, when the hologram sheet 4 is peeled from the dry film 3 of the polymer solution 2 (FIG. 1 (c)), the surface irregularities transferred to the dry film 3 are not destroyed. It is preferable that the affinity of the surface material to the dry film 3 is lower than the affinity of the hair 1 to the dry film 3. Therefore, the hologram sheet 4 is preferably one in which a metal deposition film such as aluminum is attached to the diffraction grating forming surface.

  As the diffraction grating pattern of the hologram sheet 4, the vertical type, the orthogonal type, the dot type, the wavefront type, etc. shown in FIG. it can. When the hologram sheet 4 is applied to the hair 1, if the grating pattern is vertical, the direction of the grating is preferably parallel to the longitudinal direction of the hair 1. In the case of the wavefront type, the direction of the grating However, in actual work, it is preferable that the hologram sheet 4 can be applied to the hair 1 without considering the direction of the lattice pattern. Therefore, as the hologram sheet 4, for a directional lattice pattern such as a vertical type or a wavefront type, minute regions having a diameter of about 0.1 to 1.0 mm having the lattice pattern are arranged in random directions. What is done is preferable.

  Some hair styles have areas where it is not necessary to make each individual hair independent. When applying hologram makeup to such areas, directional patterns are also preferably used. Can do. In this case, the step of loosening the hair bundle 1a shown in FIG. 1 (d) is not required, and a pattern in which an arbitrary glitter pattern such as a heart shape or a diamond shape is observed is used in the region. You can also.

  Further, the lattice pattern is preferably one in which the concave and convex patterns have the same size and the shape is inverted in the cross section, that is, the lattice pattern and the transferred pattern have the same concave / convex pattern.

  Regarding the size of the grating pattern, the grating period p is preferably 0.01 to 5.0 μm, the groove width q is 0.01 to 3.0 μm, and the groove height r is preferably 0.01 to 5.0 μm. In particular, the grating period p is preferably 0.1 to 2.0 μm, the groove width q is preferably 0.5 to 2.0 μm, and the groove height r is preferably 0.1 to 2.0 μm.

  As such a hologram sheet 4, a commercially available hologram sheet can be used, and examples thereof include CR-75, SP-08, SP-13, and SP-20 manufactured by Hologram Supply Co., Ltd.

  Although there is no restriction | limiting in particular as an aspect which interposes the polymer solution 2 between the hair 1 and the diffraction grating surface of the hologram sheet 4, as shown in FIG.1 (b), from one side of the hair bundle 1a of the hair 1 It is preferable to apply the hologram sheet 4. Thereby, compared with the case where the hair 1 is pinched | interposed with two hologram sheets, the drying time of the polymer solution 2 can be shortened.

  Further, as shown in FIG. 3, even when the polymer solution is applied to the hair bundle 1 a that has been flattened and the hologram sheet 4 is applied to one side thereof, both the hair bundle 1 a and the hologram sheet 4 may be wound around the curler 5. good. In that case, the curler 5 is preferably made of mesh from the viewpoint of speeding up drying of the polymer solution. This makes it possible to curl the hair and apply hologram makeup.

  The step of drying the polymer solution 2 interposed between the hair 1 and the hologram sheet 4 to form a dry film (FIG. 1B) is preferably performed without heating. This makes it easy to spread the polymer solution 2 on the hair 1 without agglomeration until the polymer solution 2 applied to the hair 1 is dried. It becomes easy to transfer the surface irregularities. In addition, the hair 1 can be prevented from being damaged.

  In addition, the drying time in the case of non-heating can be 10 seconds to 6 hours, preferably 30 seconds to 30 minutes.

  On the other hand, in the case of heating in the step of forming a dry film (FIG. 1B), it is preferable to set the temperature to the melting point or higher and the melting point or lower of the film-forming polymer constituting the polymer solution 2. The drying time can be shortened by heating, and the transfer property of the surface irregularities of the diffraction grating is improved particularly by setting the glass transition point or higher. On the other hand, if the temperature is too high, the polymer solution 2 melts and aggregates, making it difficult to spread as a film on the hair 1, and further, hair damage occurs due to high-temperature heat, and the film is heated. Since the diffraction grating cannot be transferred due to the deformation, it is not preferable. The preferred heating conditions depend on the type of film-forming polymer. For example, when “Plus Size DL-50” (manufactured by Kyoyo Chemical Co., Ltd.) is used as the film-forming polymer, it is 60 to 140 ° C. for 5 seconds to 3 minutes. It is preferable to set the degree.

  Although the case where the method of the present invention is applied to hair has been described above, hologram makeup can be applied to eyelashes, mustaches, nails, skin, and the like using the same polymer solution and hologram sheet.

  In this case, in order to maintain the state in which the polymer solution is interposed between the eyelashes and the hologram sheet until the polymer solution is dried, for example, as shown in FIG. 4, a hologram sheet having a curved shape of eyelashes 1 ′ The support member 6 may be used. Such a support member 6 can be formed using aluminum foil.

  The hologram cosmetic of the present invention is a combination of the above polymer solution and a hologram sheet. Thereby, the consumer can easily implement the hologram makeup method of the present invention.

  As a specific form of the hologram cosmetics, for example, a plurality of hologram sheets bundled in a strip shape and a container containing a polymer solution may be packed in one package.

  Moreover, as shown in FIG. 5, it is good also as the sheet-like cosmetic tool 8 which laminated | stacked the polymer solution layer 2a and the peeling film 7 on the diffraction grating formation surface of the hologram sheet 4 sequentially.

  As a method of using the cosmetic tool 8, first, the release film 7 is peeled off, the polymer solution layer 2a is applied to the hair, and the polymer solution 2 is kept as it is for about 30 seconds to 30 minutes, and then the hologram sheet 4 is removed. Remove. In this way, it is possible to easily apply hologram makeup to the hair.

Examples 1-3, Comparative Examples 1-2
Polymer solutions (Examples 1 to 3) or polymer emulsions (Comparative Examples 1 and 2) shown in Table 1 were prepared as film-forming liquids.

  On the other hand, the hologram film SP-01 (Sparkles) and SP-20 (Rainbow), which are imported and sold by Hologram Supply Co., Ltd., are cut into 8cm x 4cm squares as hologram sheets. Apply 0.3 ml of the active solution by dropping it with a spatula after spraying or spraying it into an aerosol form, applying it to the hair surface of 1 g of Chinese hair bundle or Chinese hair wig, and drying as shown in Table 1 After drying by the method, it was sprinkled to make each one independent.

  The luminous effect of the hair bundles or wigs of each of the examples and comparative examples thus formed with the coating was changed to an artificial solar light, that is, two types of light sources (yellow halogen lamp (TECHNO LIGHT KTS-100RSV manufactured by Kenko), and white LED maglite (ELPA). (Elpa) 1W LED light DOP-012MG)) was used to shine light from a position 10 cm perpendicular to the surface of the hair bundle or wig, and the following criteria were evaluated by visual observation of 10 monitors. The results are shown in Table 1. Moreover, about the hair bundle after film formation of Example 1, the photograph at the time of a glitter effect evaluation is shown in FIG. By adjusting the direction of the hair bundle, the circled area appeared to be rainbow-colored in many places.

[Evaluation criteria for glitter effect]
A: A holographic appearance can be clearly seen in several directions from several directions.
◯: The hologram-like appearance can be visually recognized in several colors or more by adjusting the direction.
(Triangle | delta): There is no hologram-like external appearance and white brightness is recognized slightly.
X: Hologram-like appearance cannot be recognized at all.

  From Table 1, in Examples 1-3 using the polymer solution in which the polymer is dissolved in water as the film-forming liquid agent, an excellent glitter effect was obtained, but the polymer emulsion in which the polymer was emulsified and dispersed was obtained. In Comparative Examples 1 and 2 used, the glitter effect was inferior, and in Comparative Example 3 containing no film-forming polymer, no glitter effect was observed.

In addition, when an aerosol dosage form is formed using a propellant (Examples 2 and 3), the drying time until drying is drastically shortened and the coating can be uniformly applied, and more than the glass transition point. When heated to a high temperature, the polymer can be crystallized from the molten state, so that the diffraction grating was transferred with higher accuracy than the natural drying at room temperature, and the glitter effect was improved (Example 3). Since polyurethane has a low glass transition temperature and is in a glass state at room temperature, no improvement in brightness effect due to heating was observed (Comparative Examples 2 and 3).
